Move NXP JNI and DeviceHost implementation into separate dir. (DO NOT MERGE)

Preparation for the new NCI stack. The idea is to
build either the NXP or the NCI stack, triggered
by a makefile switch. To that end, move the
DeviceHost and JNI implementations in their own
directory, so we can build them only if needed.
